英文摘要：

In this paper, a class of nonlinear viscoelastic wave equations with initial boundary value condition, delay and memory terms is considered. Under suitable conditions on the initial data, the delay term and the nonlinear damping and source terms, the blow-up in a finite time of energy of solutions is obtained. This extends earlier results in the literatures.
